Abstract
A cylinder seat for a refrigerator compressor is provided with an exhaust hole and a silencing cavity communicated with the exhaust hole, wherein a silencing counter bore which is sunken inwards from a cylinder surface is arranged on the cylinder seat, and the silencing counter bore is connected with the air inlet end of the exhaust hole. The utility model discloses structurally at current cylinder block, increase an amortization counter bore on the cylinder face, increase the amortization progression under the prerequisite that does not increase the big or small volume of cylinder block, noise cancelling effect is superior to traditional 2 grades of amortization structures in whole air current noise frequency channel, has improved the noise cancelling effect of whole air current noise frequency channel, effectual reduction compressor noise.
Description
Technical field
The utility model belongs to the Compressor Technology field, relates in particular to the cylinder block that uses on a kind of refrigeration refrigerator compressor.
Background technique
The noise that produces when reducing compressor operating, all can design silencing cavity on traditional freezer compressor cylinder block, Fig. 1 to Fig. 3 is the structural representation of a kind of freezer compressor cylinder block in the prior art, as depicted in figs. 1 and 2, cylinder face at cylinder block 100 is processed with to the inboard exhaust port 102 that extends of cylinder block, be provided with the silencing cavity 103 of two circular cylindrical cavities at exhaust port 102 rears, linked to each other by exhaust passage 104 between the silencing cavity 103.During the cylinder exhaust of compressor, the pressurized gas of compressed mistake enter first silencing cavity 103 from exhaust port 102 after entering the valve group through outlet valve, enter second silencing cavity 103 through exhaust passage 104, drain in the circulatory system by the back-shaped pipe of exhaust at last.
According to throttling noise reduction principle, progression is more, erasure effect is better, but owing to being subject to the restriction of cylinder block volume, can not infinitely increase the number of silencing cavity, existing cylinder block generally only is provided with 1 grade or 2 grades of silencing cavity, and 1 or 2 silencing cavity only are set, and is limited in the erasure effect of some pneumatic noise frequency range.Along with the raising of client to the requirement of compressor noise, how to improve the silencing cavity structure of compressor, improving erasure effect is a direction of compressor noise-reduction research.
The model utility content
The purpose of this utility model provides a kind of cylinder block that can improve the erasure effect of whole pneumatic noise frequency range, by increasing noise reduction progression, improves the cylinder block structure and realizes noise reduction.
A kind of freezer compressor cylinder block, the silencing cavity that is provided with exhaust port and is communicated with described exhaust port at cylinder block is provided with noise reduction counterbore from cylinder towards sunken inside at described cylinder block, and described noise reduction counterbore links to each other with described exhaust port inlet end.
Being shaped as of noise reduction counterbore of the present utility model is square.
As known from the above, the utility model is on existing cylinder block structure, increase a noise reduction counterbore at the cylinder face, under the prerequisite that does not increase the large small volume of cylinder block, increase noise reduction progression, erasure effect is better than 2 grades of noise-reducing structures of tradition in whole pneumatic noise frequency range, improve the erasure effect of whole pneumatic noise frequency range, effectively reduced compressor noise.
Description of drawings
Fig. 1 is the structural representation of cylinder block in the prior art;
Fig. 2 is the sectional view along A-A line among Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is an embodiment's of the utility model structural representation;
Fig. 5 is the sectional view along B-B line among Fig. 4;
Fig. 6 is the left view of Fig. 4;
Fig. 7 is as a result figure of noise simulation analysis.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in more detail.
Embodiment
Such as Fig. 3, Fig. 4 and shown in Figure 5, be processed with square noise reduction counterbore 5 from cylinder towards indent at the cylinder face of cylinder block 1, on these square noise reduction counterbore 5 inwalls, inwardly be processed with exhaust port 2, the inlet end of exhaust port 2 is communicated with noise reduction counterbore 5.Be provided with the first silencing cavity 3 that is communicated with by exhaust passage 4 at cylinder block 1 the same with the structure of the second silencing cavity 6 with the second silencing cavity 6, the first silencing cavity 3, be circular cylindrical cavity, the outlet side of exhaust port 2 links to each other with the first silencing cavity 3.The noise reduction counterbore also can adopt cylindrical or other shapes.
Cylinder block 1 of the present utility model is set up a noise reduction counterbore before exhaust port 2, the trend of air-flow is during compressor air-discharging: after the pressurized gas after the compression enter the valve group through outlet valve, air-flow flows into first the noise reduction counterbore 5 on the cylinder face, then enter exhaust port 2, enter the first silencing cavity 3 from exhaust port 2, enter the second silencing cavity 6 through the exhaust passage 4 between the silencing cavity, enter (not shown) the circulatory system from the back-shaped pipe of exhaust at last.
With reference to Fig. 7, Fig. 7 is as a result figure of noise simulation analysis, and the abscissa among Fig. 7 is frequency (Hz); Y coordinate is transmission loss amount (dB).Curve a among Fig. 7 is the erasure effect curve of different silencing cavity structures in the prior art with curve b, and curve c is that the audio cavity structure that offsets of the present utility model improves erasure effect curve afterwards.The transmission loss amount is higher to represent that then the erasure effect of baffler is better, as can be seen from Figure 7, the erasure effect of erasure effect of the present utility model in the zone of 1100～3300Hz all is better than the erasure effect of prior art cylinder block, and compare with the cylinder block of prior art, need not increase the volume of cylinder block, even compressor becomes 3 grades of noise-reducing structures by 2 grades of noise-reducing structures, improved erasure effect, and then reduced the noise of compressor.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although with reference to above-described embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that, still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the scope of technical solutions of the utility model.
